CROSS REFERENCES TO RELATED APPLICATIONS [0001] The present invention contains subject matter related to Japanese Patent Application JP 2005-024355 filed with the Japanese Patent Office on Jan. 31, 2005, the entire contents of which being incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] This invention relates to a data processing circuit and can be applied suitably, for example, to a recording and reproduction apparatus for recording and reproducing music data and particularly to a data processing circuit provided in a data processing apparatus such as a personal computer and a music reproduction apparatus. [0003] A conventional disk reproduction apparatus includes a system controller for controlling the entire disk reproduction apparatus such that music data (hereinafter referred to as compressed music data) compression coded in advance and recorded on a magneto-optical disk are read out at a first rate for each predetermined recording unit and also address data of such compressed music data for each recording unit (hereinafter referred to as recording unit compressed music data) on the magneto-optical disk is read out. Then, the disk reproduction apparatus temporarily and cumulatively stores the recording unit compressed music data successively read out from the magneto-optical disk in this manner in a coordinated relationship with the address data into a RAM (Random Access Memory) serving as a buffer memory. [0004] Further, the disk reproduction apparatus successively reads out the recording unit compressed music data at a second rate lower than the first rate from the RAM and decompresses the read out compressed music data by means of a data decompression circuit. Then, the disk reproduction apparatus converts music data obtained by the decompression from digital data into an analog signal and signals the analog signal to a headphone or the like. Consequently, even if it is temporarily rendered difficult to read out the recording unit compressed music data from the magneto-optical disk by vibration of the disk reproduction apparatus applied from the outside, the disk reproduction apparatus can continue to successively read out the recording unit compressed music data cumulatively stored in the RAM from the RAM for a period of time until reading out of the recording unit compressed music data is re-started. Accordingly, such a disk reproduction apparatus as described above prevents intermittent interruption of sound of the music outputted from the headphone or the like when the recording unit compressed music data are read out from a magneto-optical disk and processed for reproduction. A disk reproduction apparatus of the type described is disclosed, for example, in Japanese Patent Laid-Open No. Hei 6-150540 (pages 2 and 4 and FIG. 3, hereinafter referred to as Patent Document 1). SUMMARY OF THE INVENTION [0005] Incidentally, in a disk reproduction apparatus having such a configuration as disclosed in Patent Document 1, upon reproduction of recording unit compressed music data, the system controller reads out and acquires also attribute information necessary for a decompression process of compressed music data from the magneto-optical disk. Then, in the disk reproduction apparatus, when recording unit compressed music data read out from the RAM are to be provided to the data decompression circuit, the system controller signals also the attribute information corresponding to the recording unit compressed music data to the data decompression circuit. Consequently, in the disk reproduction apparatus, the data decompression circuit decompresses the recording unit compressed music data precisely using the corresponding attribute information. [0006] However, in the disk reproduction apparatus, the system controller transfers various control instructions to a RAM control circuit, the data decompression circuit and so forth to control temporary storage and reading out processes of the reading unit compressed music data into and from the RAM and a decompression process and other necessary processes for the recording unit compressed music data. Further, in the disk reproduction apparatus, while the system controller discriminates the recording unit compressed music data read out from the RAM, it selects and transfers corresponding attribute information to the data decompression circuit in a timed relationship with the decompression process of the recording unit compressed music data. Therefore, the disk reproduction apparatus is disadvantageous in that, when recording unit compressed music data are to be reproduced, the system controller must transfer a great number of control instructions and pieces of attribute information and so forth to the RAM control circuit, data decompression circuit and so forth and must bear a heavy processing load. [0007] In the present invention, it is desirable to provide a data processing circuit which can process data precisely while the processing load to a controlling source is reduced. [0008] In order to attain the desire of the present invention, according to an embodiment of the present invention, there is provided a data processing circuit, including an information detection section configured to detect, from within data read out from a buffer memory and having attribute information, the attribute information, a data processing section configured to process, in response to the attribute information detected by the information detection section, data corresponding to the attribute information, and a real time control section configured to real time control at least one of the information detection section and the data processing section in accordance with a control instruction for real time processing inputted from the outside. [0009] In the data processing circuit, since attribute information included in data in advance is used for processing of the data, the data can be processed precisely using the corresponding attribute information without causing a controlling source for the data processing circuit to execute such a complicated process that, while it discriminates the data in accordance with the process of the data, it selects and transfer corresponding attribute information. Further, when a request for real time processing is received from the outside, the data processing circuit receives a control instruction for the real time processing transferred from the controlling source at the point of time of the request and real time controls a corresponding element. Therefore, the data processing circuit can cope precisely with a request for real time processing. [0010] According to another embodiment of the present invention, there is provided a data processing apparatus, including a data processing circuit having a buffer memory configured to temporarily store data having attribute information, an information detection section configured to detect the attribute information from the data read out from the buffer memory and having the attribute information, a data processing section configured to process, in response to the attribute information detected by the information detection section, data corresponding to the attribute information, and a real time control section configured to real time control at least one of the information detection section and the data processing section in accordance with a control instruction for real time processing. [0011] In the data processing apparatus, since the data processing circuit detects attribute information included in data in advance and uses the attribute information for processing of the data, the data processing circuit can process the data precisely using the corresponding attribute information without causing a controlling source for the data processing circuit to execute such a complicated process that, while it discriminates the data in accordance with the process of the data, it selects and transfer corresponding attribute information. Further, when a request for real time processing is issued, the data processing apparatus transfers a control instruction for the real time processing transferred from the controlling source at the point of time of the request so as to real time control a corresponding element. Therefore, the data processing apparatus can cope precisely also with a request for real time processing. [0012] According to a further embodiment of the present invention, there is provided a data processing method, including an information detection step of detecting, from within data read out from a buffer memory and having attribute information, the attribute information, a data processing step of processing, in response to the attribute information detected at the information detection step, data corresponding to the attribute information, and a real time control step of real time controlling at least one of the processes executed at the information detection step and the data processing step in accordance with a control instruction for real time processing inputted from the outside. [0013] In the data processing method, since, upon data processing, attribute information included in data in advance is detected and used for processing of the data, the data can be processed precisely using the corresponding attribute information without causing a controlling source for the data processing to execute such a complicated process that, while the data are discriminated in accordance with the process of the data, corresponding attribute information is selected and transferred. Further, in the data processing method, when a request for real time processing is issued from the outside, a control instruction for the real time processing transferred from the controlling source at the point of time of the request is received to real time control a corresponding process. Therefore, it is possible to cope precisely also with a request for real time processing. [0014] According to a still further embodiment of the present invention, there is provided a data processing control method, including a temporarily storing step of signaling, to a data processing circuit including a buffer memory configured to temporarily store data having attribute information, an information detection section configured to detect the attribute information from the data read out from the buffer memory and having the attribute information, a data processing section configured to process, in response to the attribute information detected by the information detection section, data corresponding to the attribute information, and a real time control section configured to real time control at least one of the information detection section and the data processing section in accordance with a control instruction for real time processing, the data having the attribute information so as to be temporarily stored into the buffer memory, and a control instruction signaling step of signaling, when the attribute information is detected from within the data read out from the buffer memory and having the attribute information by the information detection section of the data processing circuit and the data corresponding to the attribute information detected by the information detection section are processed in response to the attribute information by the data processing section, the control instruction for real time processing to the real time control section of the data processing circuit to cause the real time control section of the data processing circuit to perform the real time control of at least one of the information detection section and the data processing section in accordance with the control instruction. [0015] In the data processing control method, since the data processing circuit is controlled to detect attribute information included in data in advance and use the attribute information for processing of the data, the data processing circuit can process the data precisely using the corresponding attribute information without causing a controlling source for the data processing circuit to execute such a complicated process that, while the data are discriminated in accordance with the process of the data, corresponding attribute information is selected and transferred. Further, in the data processing control method, when a request for real time processing is issued, a control instruction for the real time processing is transferred from the controlling source to the data processing circuit at the point of time of the request to real time control a corresponding element. Therefore, it is possible to cope precisely also with a request for real time processing. [0016] According to a yet further embodiment of the present invention, there is provided a storage medium on which a data processing program is recorded, the data processing program causing a data processing circuit to execute an information detection step of detecting, from within data read out from a buffer memory and having attribute information, the attribute information, a data processing step of processing, in response to the attribute information detected at the information detection step, data corresponding to the attribute information, and a real time control step of real time controlling at least one of the processes executed at the information detection step and the data processing step in accordance with a control instruction for real time processing inputted from the outside. [0017] In the data processing program recorded on the storage medium, since the data processing circuit is controlled to detect attribute information included in data in advance and use the attribute information for processing of the data, the data processing circuit can process the data precisely using the corresponding attribute information without causing a controlling source for the data processing circuit to execute such a complicated process that, while the data are discriminated in accordance with the process of the data, corresponding attribute information is selected and transferred. Further, in the data processing program, when a request for real time processing is issued on the outside, the data processing circuit receives a control instruction for the real time processing transferred from the controlling source to the data processing circuit at the point of time of the request to real time control a corresponding element. Therefore, it is possible for the data processing circuit to cope precisely also with a request for real time processing. [0018] According to a yet further embodiment of the present invention, there is provided a storage medium on which a data processing control program is recorded, the data processing control program causing a data processing circuit, which includes a buffer memory configured to temporarily store data having attribute information, an information detection section configured to detect the attribute information from the data read out from the buffer memory and having the attribute information, a data processing section configured to process, in response to the attribute information detected by the information detection section, data corresponding to the attribute information, and a real time control section configured to real time control at least one of the information detection section and the data processing section in accordance with a control instruction for real time processing, to execute a temporarily storing step of signaling the data including the attribute information to the data processing circuit so as to be temporarily stored into the buffer memory, and a control instruction signaling step of signaling, when the attribute information is detected from within the data read out from the buffer memory and having the attribute information by the information detection section of the data processing circuit and the data corresponding to the attribute information detected by the information detection section are processed in response to the attribute information by the data processing section, the control instruction for real time processing to the real time control section of the data processing circuit to cause the real time control section of the data processing circuit to perform the real time control of at least one of the information detection section and the data processing section in accordance with the control instruction. [0019] In the data processing control program recorded on the storage medium, since the data processing circuit is controlled to detect attribute information included in data in advance and use the attribute information for processing of the data, the data processing circuit can process the data precisely using the corresponding attribute information without causing a controlling source for the data processing circuit to execute such a complicated process that, while the data are discriminated in accordance with the process of the data, corresponding attribute information is selected and transferred. Further, in the data processing control program, when a request for real time processing is issued, the data processing apparatus transfers a control instruction for the real time processing transferred from the controlling source to the data processing circuit at the point of time of the request to real time control a corresponding element. Therefore, it is possible for the data processing circuit to cope precisely also with a request for real time processing. [0020] In summary, with the data processing circuit, the data processing method and the storage medium on which the data processing program is stored, from data read out from a buffer memory and including attribute information, the attribute information is detected, and the data in which the attribute information is included are processed in response to the detected attribute information. Then, at least one of the information detection process and the data processing process is real time controlled in accordance with a control instruction for real time processing inputted from the outside. Consequently, the data can be processed precisely using the corresponding attribute information without causing a controlling source for the data processing to execute such a complicated process that, while the data are discriminated in accordance with the process of the data, corresponding attribute information is selected and transferred. Further, also a request for real time processing can be coped with precisely in accordance with a control instruction for real time processing transferred from the controlling source. Thus, the data can be processed precisely while the processing load to the controlling source is reduced. [0021] Further, with the data processing apparatus, the data processing control method and the storage medium on which the data processing control program is stored, the data processing circuit includes a buffer memory configured to temporarily store data having attribute information, an information detection section configured to detect the attribute information from the data read out from the buffer memory and having the attribute information, a data processing section configured to process, in response to the attribute information detected by the information detection section, data corresponding to the attribute information, and a real time control section configured to real time control at least one of the information detection section and the data processing section in accordance with a control instruction for real time processing. Therefore, the data processing circuit can process the data precisely using the corresponding attribute information without causing a controlling source for the data processing circuit to execute such a complicated process that, while the data are discriminated in accordance with the process of the data, corresponding attribute information is selected and transferred. Further, also a request for real time processing can be coped with precisely by transferring a control instruction for real time processing from the controlling source to the data processing circuit. Thus, the data can be processed precisely while the processing load to the controlling source for the data processing circuit is reduced. Continue reading...
